don't panic mr mainwaring!

Looking at Mt.Gox there is a big buy @ 16, i think if that gets filled its looks like there is very little buying power left to keep the price up.

Why is there such a large proportion of sells compared to buys, is that normal?

cschmitz your concerns make a lot of sense to me. What if dark pools were only hidden for a certain period of time, say 24/48hrs, this would at least go some way to reducing mt.gox's advantage?

The way i see it is saving is accumulating a currency in the hope of buying something which you cannot currently afford. Hoarding is accumulating currency with no intention of buying something, purely based on the expectation that the value of the currency will increase. This is potentially bad because if the value of the currency drops the hoarders loose confidence and may panic sell, causing a crash.  

Thought i'd give it a whirl, just put in 0.47 jackpot now 0.98
